Bun vs Deno: which should you choose?
Bun optimizes raw speed and Node compatibility, bundling a package manager, test runner, and transpiler into one fast binary. Deno emphasizes security and standards, with permissions-by-default, native TypeScript, and a Web-standard API surface. Pick Bun for performance and drop-in Node migration; pick Deno when secure-by-default execution and first-class TypeScript matter more.
